At about 9:15 a.m. on May 31, 2012, Jeff Blaser, age 38, of Damascus, called 911 after seeing a female school-bus driver in distress alongside SE Sunnyside Road near SE 157th Avenue in Happy Valley.

When Mr. Blaser stopped to assist, he saw that the driver -- identified as Alice Scoggin, age 68, of Portland -- was being assaulted by a juvenile male. He later reported the student was biting Ms. Scoggin and also tried to bite Blaser.

Happy Valley Police arrived at 9:18 a.m. and called for a medical response, as the bus driver was bruised and bloody.

The student -- not named, approximate age 10-12 years -- reportedly had bit Ms. Scoggin multiple times in the arm and face, causing her injuries. The student also attempted to bite the deputy as he was taking him into custody.

The student was taken into protective custody. Deputies learned during the investigation that the student has autism.
